Re: Sharpness in Tiff Scans

I have done a number of scans of 35mm and m/f frames, using a Nikon
Coolscan and an Epson 4990. On the Nikon I've used their scanning
software, on the Epson SilverFast.

Each image has been scanned twice. First 2000 dpi jpg; second 4000 dpi
tiff. Apart from that all other settings were the same.

I am puzzled because in every case on enlargement the tiffs look
markedly inferior to the jpgs which are sharper. I had expected the
opposite to be the case.

Can anyone throw light on why this might be, and more importantly
suggest a solution? All suggestions gratefully received.

The jpegs are probably sharpened by the scanning software, whereas the tiffs are not.

Sharpening the tiffs in Photoshop will produce as good or better than the jpegs.
